To all whom it ma concern: Be it known t at I, Jmm L. WEN'rz, a

citizen of the United States, and a resident of Passaic, in the county of Passaic and State of New Jersey, have invented a new and Improved Conveyer, of which the following 1s a full, clear, and exact description.

Among the principal objects which the present invention has in view are: to provide a portable conveyor having self-actuated means for supplying thematerial to the conveyer; to prevent spilling the load being carried; to-prevent the" outer edges of the conveying belt from sagging between the rollers sup rting thece'ntral section of the conveying alt; to prevent the load carried on the belt of the conveyer from traveling downward on the conveyor; to avoid accumulation of material on the under or pulley-engaged side of the conveying belt; to avoid accumulation of material on the idler drum supporting the conveying belt at the receiving end of the conveyer; and to avoid accumulation of material between -the top and bottom extensions of the belt at the receiving end of the conveyer.

Drawings.

Figure 1 is a side view of a conveyer constructed and arranged in accordance; with the present invention, the same being shown Fig. 5 is a side view of anend fragment ofthe conveyer frame and a fragment of a pintle bar in position to be operated upon by a feedin vibrator with which the conveyor is rovi ed; ig. 6 is a detail view on an enlarged scale in cross section,.the section being taken as o the line 6-6 in Fig. 5; Y

Fig. 7 is a detail view on an enlarged scale tacha showing a fragment of the receiving end of the conveyor and an eccentric vibrator disposed thereon; i

, Fig. 8 is a similar view showin a modified form of vibrator and feed mem er for the conveyor.

Demption.

As seen in the drawings, a conveyor constructed in accordance with the present in vention has a frame which is partially su ported and carried on wheels 15. The whee s 15 are mounted on an axle 16. The axle 16 is mounted in bearings extendedbracket of the standards 18 and the conveyor frame supported thereby. The conveyor frame is suitably mounted through cross bars 20, to bars 21, the ends 22 whereof are tubular to act as sockets for lifting handles 23. The handles 23 are dely secured to the ends 22 and are employed to permit an attendant or operator to lift the receiving end of the conveyer.

The wheels 15 are so placed that when the lower end of the conveyer frame is raised, the center of gravity of the conveyor frame is disposed substantially in line with the axle 16, or, in other words, the total "weight of the conveyer is poised on the carrying wheels 15.

When theconveyer is actively disposed, the handles 23 are withdrawn from engage ment with the socketed ends 22.

The frame of the conveyer, as best shown in Figs. 1 and 3 of the drawings, is constructed of angle bars 24 and 25. These bars eitend the full length of the frame and are held in parallel spaced relation by braces 26 and cheek plates 27 The plates 27 operate to prevent coal or other material being handled by the eonveyer from assing to the inner side thereof to be deposited on the under or inner side of the conveyor belt 28. The conveyor belt 28 extends lengthwise of the frame formed by the angle irons 24 and 25, and is supported mainly by the drums 29 and 30. The drum 30 is an idler and is located between a shoeplate 31'and a flexible apron32. The drum 29, as shown best in Fig. 2, has bearin in sliding blocks 33. To adjust the bloc 33 is the function of the feed screws 34, which engage the blocks 33 to move the same lengthwise of and in guided relation to the angle bars 24 and 25.

As best seen in Figs. 3 and 4 of the drawings, the central section of the belt 28 is supported by rollers 35. The rollers 35 have pintle journals for which are provided bearl'ngs in the supporting rails 36. The outer edges of the belt 28 overhang and rest upon the rails 36, which maintain the edges of said belt in fixed and close ap roximation to the lower edge of the cheek rds '37, and prevent sagging of the edges of the belt between the rollers 35. The belt 28 is suitably rovided at intervals with cleats 38. The c eats 38 are preferably constructed of rubber. As seen best in Fig. 3 of the drawings, the cleats 38 extend above the belt 28 and between the cheek boards 37. The cleats serve in the active practice of the conveyer, to maintain the belt 28 in alinement and to impart vibration to apron 32.

The belt 28 is continuous and extends over the drum 29, which is driven by means of transmission chains 39 and 41, and a motor 40. The motor 40 is of any convenient desired type, and is preferably mounted on the platform constructed between the bars 21, and is operatively connected with the chain 39 by a driving belt or chain 41 and transmission sprockets 43 and jack shaft 42. The plates 27 and 31, and nosing 44' form a boot for the conveyer which prevents the interference by: the material being handled, with the under side of the belt where the same turns around the drum 30.

The nosing 44 is rigid and is fixedly connected with the apron 32. The apron 32 rests over the lowerend of the belt 28 to accommodate the action of the said belt and of the cleats 38 mounted thereon. Through the agency of the apron 32. and the vibration imparted thereto by said cleats, the coal or other material being handled is agitated and spread prior to being delivered to the belt 28, to be conveyed to the delivery end thereof. The agitation referred to as being imparted throu h the agency of the apron 32, 1s augmente by a tappet cam or eccentric 45 mounted at the end of the shaft bearing the drum 30 and extending beyond the plates 27. The cam 45, as seen best in Fig. 5 of the drawings, is employed in conjunction'with a pintle bar 46. The pintle bar 46 in the present construction isusually formed from one of the handle bars'23. It is furnished with a pointed end for driving into the 55. As best shown in Fig. 2 of the ground or floor over which the conveyer is working.

The operator having set the pointed end of the bar 46, moves the bar into the path of the eccentric 45, so that'the same engages the said bar as the drum 30 rotates. It is obvious that the result of such action is to break up any solid formation of the pile being conveyed, and to enforce the nosing 44 into the pile until the upper stratum thereof rolls upon the apron 32 and belt 28.

In Fig. 7 of the drawings, a modified form of the eccentric is shown, the modification embodying a disk 47, which has an arcuate slot 48. ivotally mounted on the disk 47, is a bearing plate 49. A perforated boss 50 extends from the plate 49. The axis of the perforation in the boss 50 coordinates with the center of the slot 48, when the plate 49 swings on the'pivot 51 with which it is rovide The boss 50 tightly fits the on of the pintle of the drum 30 to be rotated therewith. The plate 49 is perforated at the end opposite the pivot 51 to receive a coupling pin 52. The pin 52 also engages any one of the sockets 53 with which the disk 47 is provided. The sockets 53 are arranged in a line concentric with the pivot 51 and median line of the slot 48. It is evident that as the pin 52 is disposed in one or other of the perforations 53, the eccentric arrangement of the disk 47 is modified relatively to the center of the drum 30. In this manner, provision is made for increasing or diminishing the vibratory action of the disk 47 on the bar 46.

' In Fig. 8 of the drawings, a modified arrangement of the eccentric is disclosed. In this arrangement, an ovate cam 54 is keyed to the drum 30. The long diameter of .the cam 54 is greater than the distance between the axis of the drum 30 and the bottom of the shoe plate 31. As a result of this construction, the cam 54 strikes upon the floor or ground on which the plate 31 is resting and lifts the same and the coal or other material superimposed thereon.

It will be understood that the employment described is optional.

To prevent the back flow of the load carried on the belt 28, there are provided a mug rawings, the aprons 55 are pivotally mounted on shafts 56, and in bearings therefor formed in the brackets 57.

Any dislodged particles that roll back from the belt 28 and above the aprons 55, are prevented thereby from rolling backward to the receiving endof the conveyer.

As set forth hereinbefore, the plates 27 and the shoe plate 31 constitute a conveyer boot. Part of the function of the apron 32 is'to permit any'material which might find thereof to escape to be dislodged or forced upward by the cleats 38. It is obvious that the apron 32 will lift and relieve m pressure from below imparted in the manner indicated.

While the cheek boards 37 and supporting rails 36 operate efliciently to prevent any lodgment of particles or the accumulation of grit and dust on the inner side of the belt 28 and on the lower reach thereof, insuch operations as those in which the conveyer is employed, it is impossible to entirel exclude the particles of grit and dust. I such material reaches the drum 30, it is obvious that it will adhere to the surface thereof and accumulate to the ultimate efl'ect that the diameter of the drum and coating thereon, is increased and the perfect working adjustment of the apparatus might be destroyed. To avoid this, a scraper plate 58 is (prov ded.

As seen best in Fig. 4 of the rawings, the plate 58 has a scraping end disposed in close approximation'to the drum 30. The scrapin end ofthe late 58 is supported by an 'an e iron 59. he lower end of the angle lI'Ol'l 59, in service rests close to the upper surface of the lower stretch of the belt 28. This serves to remove any ad- .hesions on the inner surface of the belt 28,

which have escaped the scraping edge of the bolster 60, which, as shown, sup orts the tail end of the late 58. The bo sed in receivingrelation to the plate 58.

he outer end of the shelves 61 extend through openings 62 shown in Fig. 1 of the drawings. If any material passes the'scra ing edges of the bolster 60 and the ang e iron 59 and finds lodgment on the drum 30, the scraping end of the plate 58 serves to dislod e the same. The material thus remov from the drum 30, is drawn by the belt 28 over the plate 58 and delivered to the shelves 61, and in turn is delivered by the said shelves beyond the plates 27 and outside of the apparatus.

Operation.

When operating with a conveyer constructed and arranged as above described and as shown in the accompanying draw-' end of the conveyer.

r 60 also supports inc ined shelves 61, which are dishandles 23 are then removed and the attendant presses the nosin 44 of the conveyer into the pile, using t e bar 46 for this purpose. f .a wagon or othervehicle is to be loaded from the dump, the wagon or vehicle is. brought under the delivery The motor 40 is. then started. The attendant usi the pinch bar 46 or one of the handles 3, as indicated, presses against the cam 45, forc in the nosing 44 well under the dump or pi e, where the surface material will flow to the apron 32 and belt 28 incident to the vibrating operation of the eccentric 45, as above described.

The material of the dump flowin as it does to the conveyer, is carried there y over the head or delivery end of the conveyer, and de osited in the wagon or vehicle. When t e vehicle has. received its complement or load, the motor 40 is discontinued and the conveyer brought to rest to await the disposition of a second vehicle at the receivin station.

If t e vehicle is low or for an reason it is determined to change the inciination of the conveyer and supporting frame therefor, this israccomplished by withdrawing the pins from the perforations 19 in which they rest for supporting the standards 18. The standards are then moved to the desired in- 'clination and the supporting pins reinstated.

It will be noted that in this adjustment, the

operative relation of the belt 41 is not disturbed.
